You need a pokeball at least though you can buy upgrades like great balls and ultra balls but you can also buy unique pokeballs like repeat ball, timer ball and receive net ball and nest ball and luxury ball. All of these can be used to catch a Pokemon an easy way to catch a Pokemon is weaken it then inflict a status problem on the Pokemon like sleep or paralyze then throw the pokeball some Pokemon are hard to catch so it may take longer to catch then others you may have to use an upgraded Pokemon usually stronger Pokemon make you have to use upgraded pokeballs. Also if the Pokemon is weaker use a nest ball if its a bug or water type use a net ball if you caught or owned this Pokemon before use a repeat ball lastly if the battle has lasted a long time use a timer ball.
